6 important things you should know about how your brain learns

I always had a keen eye for the brain and psychology, but not in an American Psycho way. It wasn´t until recently I started to read more about it. At the moment I´m reading a fascinating book named Batman and psychology which I warmly recommend. And the other day a very interesting blog post crossed my path which I´m now reblogging. It´s originally written by Belle Beth Cooper on the Crew blog and it gives us a bit of insights of how we learn and action points.

Whether you want to learn a new language, learn to cook, take up a musical instrument, or just get more out of the books you read, it helps to know how your brain learns. While everyone learns slightly differently, we do have similarities in the way our brains take in new information, and knowing how this works can help us choose the most efficient strategies for learning new things.

Here are six things you should know about the brain’s learning systems.

1. We take in information better when it’s visual

Think about that for a minute. Half of your brain power goes to your eyesand the processes in your brain that turn what you see into information. The other half has to be split up among all the other functions your body has.

Vision is not only a power-hungry sense, but it trumps our other senses when it comes to taking in information.

A perfect example of this is an experiment where 54 wine aficionados were asked to taste wine samples. The experimenters dropped odorless, tasteless red dye into white wines to see whether the wine tasters would still know they were white based on the taste and smell. They didn’t. Vision is such a big part of how we interpret the world that it can overwhelm our other senses.

Another surprising finding about vision is that we treat text as images. As you read this paragraph, your brain is interpreting each letter as an image. This makes reading incredibly inefficient when compared to how quickly and easily we can take in information from a picture.

More than just static visuals, we pay special attention to anything we see that’s moving. So pictures and animations are your best friends when it comes to learning.

Action: Find or make flash cards with images on them. Add doodles, photos, or pictures from magazines and newspapers to your notes. Use colors and diagrams to illustrate new concepts you learn.

2. We remember the big picture better than the details

When you’re learning lots of new concepts, it’s easy to get lost in the barrage of information. One way to avoid being overwhelmed is to keep referring back to the big picture. This is probably where you’ll start with something new, so coming back to explore how the new concept you just learned fits into that big picture can be helpful.

When the brain takes in new information, it hangs onto it better if it alreadyhas some information to relate it to. This is where starting with the gist of an idea can be helpful: it gives you something to hang each detail on as you learn it.

I read a metaphor about this concept once that I loved: imagine your brain is like a closet full of shelves: as you add more clothes they fill up more of the shelves and you start categorizing them.

Now if you add a black sweater (a new piece of information) it can go on the sweater shelf, the black clothes shelf, the winter clothes shelf, or the wool shelf. In real life you can’t put your sweater on more than one shelf, but in your brain that new piece of information gets linked to each of those existing ideas. You’ll more easily remember that information later because when you learned it you related it to various other things you already knew.

Action: Keep a large diagram or page of notes handy that explains the big picture of what you’re learning and add to it each major concept you learn along the way.

3. Sleep largely affects learning and memory

Studies have shown that a night of sleep in-between learning something new and being tested on it can significantly improve performance. In a study of motor skills, participants who were tested 12 hours after learning a new skill with a night of sleep in-between improved by 20.5%, compared to just 3.9% improvement for participants who were tested at 4-hour intervals during waking hours.

Naps can improve learning just like a full night of sleep can. A study from the University of California found that participants who napped after completing a challenging task performed better when completing the task again later, compared to participants who stayed awake in-between tests.

Sleeping before you learn can also be beneficial. Dr Matthew Walker, the lead researcher of the University of California study, said “Sleep prepares the brain like a dry sponge, ready to soak up new information”.

Action: Try practicing your new skill—or reading about it—before going to bed or taking a nap. When you wake up, write some notes on what you remember from your last study session.

Sleep deprivation is a scary thing. Because we don’t fully understand sleep and its purpose yet (though we have some ideas) we don’t always respect our need for sleep.

But although we can’t say definitively what sleep does for us, we know what happens if you don’t get enough. Sleep deprivation makes us play it safe by avoiding risks and leaning on old habits. It also increases our likelihood of being physically injured, since our bodies don’t perform as well when we’re tired.

Most importantly for learning: sleep deprivation can cut your brain’s ability to take in new information by almost 40%. Compared to getting a good night’s sleep and waking up refreshed and ready to learn, an all-nighter doesn’t seem worth the effort.

Action: Forget all-nighters. Save practice and study sessions for days when you’re alert and well-rested. And definitely avoid sleep deprivation right after learning something new.

5. We learn best by teaching others

When we expect to have to teach other people what we’re learning, we take in new information better. We organize it better in our minds, remember it more correctly, and we’re better at remembering the most important parts of what we’ve learned.

One study told half the participants they would be tested on the information they were learning, and told the other half they would have to teach someone else what they learned. Both sets of participants were tested on the information and didn’t have to teach anyone else, but the subjects whothought they’d be teaching others performed better on the test.

The study’s lead author, Dr. John Nestojko, said the study implied that students’ mindsets before and during learning can make a big difference to how well we learn new information. “Positively altering a student’s mindset can be effectively achieved through rather simple instructions,” he said.

Though we don’t realize it, learning with the idea that we’ll have to teach this information later tends to invoke better methods for learning subconsciously. For instance, we focus on the most important pieces of information, the relationships between different concepts, and we carefully organize the information in our minds.

Action: Keep a notebook or blog where you write about what you’ve learned. Write about each new concept you learn as if it’s a lesson for others.

6. We learn new information better when it’s interleaved

A common learning approach is what UCLA researcher Dick Schmidt calls ‘block practice’. When you practice or focus on learning one particular thing over and over, that’s block practice. For instance, you might study history for a few hours in a row, or practice just your serve in a tennis lesson.

Schmidt advocates a different approach to learning called interleaving, which mixes up the information or skills you practice. Another UCLA researcher, Bob Bjork, studies interleaving in his psychology lab. One of his experiments involves teaching participants about artistic styles by showing them a series of images on a screen. Some of the participants are exposed to block practice of artistic styles (all 6 examples of a painter’s style are shown before moving on to another painter’s style), while others have their images interleaved (examples of different painter’s styles are mixed in together).

When the two groups are tested afterwards on how well they can recognize a painter’s style in a painting they haven’t seen before, the interleaving group usually scores around 60%, while the block group scores around 30%.

Surprisingly, around 70% of the participants in this experiment say they think the block practice was most effective in helping them learn. Clearly we have some work to do to understand what helps us learn best.

Bjork believes interleaving works better because it plays into our natural abilities to recognize patterns and outliers. When applied in the real world it also provides an opportunity for us to review information regularly, as we interleave what we already know with new information.

Some examples for interleaving could be cycling through three different subjects you need to study before exams, practicing speaking, listening, and writing skills of a foreign language in tandem rather than in blocks, or practicing your forehand, backhand, and serves in a single tennis lesson rather than setting aside one lesson for each.

Action: When you’re learning or practicing a new technique, practice it interleaved with other techniques. For instance, if you’re practicing a particular golf swing, practice other swings at the same time to mix it up. If you’re learning new information, mix in information you already know—old vocabulary words and new when you’re learning a foreign language, for instance.

As Bob Bjork says, we all need to become smarter learners. “In almost any job, you have to keep managing some new kind of technology,” he said, so “just knowing how to manage your own learning is very important”.
